I want to measure field queue length at a four legged intersection at all the legs, which will be used to calibrate and validate in VISSIM.
What is the best method? Two legs are six lanes and two are four lanes.
Relevant answer
Answer
There are two options for measuring the queue length of vehicles in VISSIM.
  • First, you can use the "Queue Counter" and place it on each road lane you wish the queue to measure. This method is a bit tricky, if you place it too close to the intersection and it turns out to be a very long queue, the vehicles behind the "queue counter" may not be captured by VISSIM.
  • Another feature is to use "Link Evaluation" just by activating it (put a checkmark in the blank box in the Evaluation menu). Then, you will automatically generate queue and delay results.

Hello everybody,
I am simulating a 2D model of microparticles motion in a microdevice using laminar flow and particle tracing modules in COMSOL. The device has three inlets and two outlets. The particles are just injected from the central inlet. There are some pillars in the device and I defined "bounce" B.C at their walls. I set different pressures at the inlets (e.g., 2.2[mbar], 2[mbar], 1.8[mbar]), however, in some cases when I increase or reduce the pressures, particles disappear at the beginning from the inlet so that I cannot see particles in the device during the running. Sometimes at the end I also receive the following error:
"Some particles have been removed from the simulation because of a failure in finding the wall intersection."
I would be grateful if a one could help me with this issue.
Best,
Zohreh
Relevant answer
Answer
Hi
my first approach would be to check the mesh and geometry at the particle inlets. However, when Comsol recognizes your fluid chamber as one domain, it is unlikely that the geometry itself is flawed. But maybe a diffrent mesh helps.
Is there a reason for defining the inlet pressure rather than an inlet velocity? Because when the pressure difference from inlet A to B becomes too big, a flow from one inlet to the other inlet will rise. You could suppress this by changing the boundary condition to velocity/volume flow normal to the inlets.
Good luck

I'm annotating CT scan slices from CQ-500 dataset with ITK-snap. One slice contains two labels(Subarachnoid and Intraparenchymal) in the same area. Here is the link: https://ibb.co/FJpyVZF
I'm trying to annotate this slice with ITK-snap. Since two labels are overlapping, the intersection area in the slice should contain both labels. But it shows it only contains the label which has been drawn last. Since the Subarachnoid area was drawn last over the Intraparenchymal area, the final segmented image only shows it contains Subarachnoid in the intersection region. I'm attaching the annotated slice (https://ibb.co/F3TrXtq) and segmented slice (https://ibb.co/sRgdndY) to clear my point.
What can I do to make the intersection area contain two labels? I'm new to ITK-Snap, so any help will be great.

Answer
Thank you, Vikas Ramachandra . I have never done labeling with Pydicom, I will surely try it. I have solved my initial problem with 3DSlicer. Unfortunately, overlapping segmentation can only be done in 4D volume in 3dSlicer. I don't want to dive into 4D volume now, so I was thinking what if I create separate Nifti files for each separate label and train them in a 3D model (maybe U-Net). Would not that be okay? And what would be the appropriate loss function for this task as my dataset is very imbalanced?

Hello, I have 91 items ranked by groups of participants. The rank lists for each group are therefore all the same length and contain identical items.
I know I can perform correlation measures (e.g. Kendall's Tau) or intersection measures (e.g. Rank Biased Overlap) to determine how similar the rankings from different groups are, in general. But are there any statistical tests available to tell me which items in the lists are ranked significantly differently?

Hello everyone. I hope all of us get well during the pandemic.
I have conducted an analysis using binary logisitc regression to investigate the intersection between gender (male, female) and official language efficiency (English, French, both English and French) with the outcome: youth's sense of belonging. However, I am unsure of two considerations that needed your comments.
First, I found a significant contribution of the intersection between gender and official language efficiency with the outcome (e.g. youth' sense of belonging). Male, speaking English as the reference group. However, the results showed no significant differences among the variable's levels. In such a case, is it fine if we still report it as a significant result?
Second, in the same situation, I found nonsignificant contributions to the entire intersection (visible minority status intersecting official language efficiency) with the outcome. However, I found a significant difference among it level. For example, compared to youth not experiencing visible minority status speaking English (the reference group), youth with visibility status speaking French are more likely to have a strong sense of belonging. In this case, is it appropriate to report it?

Solution to the problem:
Consider B´such that B is a midpoint of AB´. We obtain two pairs of similar triangles:
  1. In the triangle AB´C we have B´C=2BM (=2BN).
  2. In NB´C, the ratios BP : B´C = NP : NC.

Hello
My geometry which I want to apply mesh on it is an in-pipe turbine. There are two bodies: a turbine and a pipe. The blades are surrounded by a sphere that is subtracted from the pipe which indicates that different analysis should be applied on inside and outside of this sphere (figure 1). My meshing strategy implemented as follows: 1- An edge sizing which it’s type is element size (0.005 m) for the intersection of the blades and discs. 2- two edge sizing that their number of divisions is 20. One of them is applied for the blades’ edges and the other one is applied for the disc’s edges. 3- an inflation for the surface of the sphere. 4- A face meshing for the pipe. 5- a face sizing for the inner and outer pipe surfaces and inlet and outlet regions. 6- A face sizing for the sphere. 7- an inflation for the pipe’s walls (figure 6).
At last, the challenges are:
1- the inner volume of the sphere doesn’t mesh for small edge sizing (figure 4).
2- the maximum skewness is 1 (figure 7), the low-quality elements are placed at the location of the intersection of the discs and the blades (figure 5).
3- I can’t apply face meshing on discs.
I will be so thankful if you help me. Should I change my meshing strategy?
Relevant answer
Answer
Hi, I highly recommend using ICEM CFD for such complicated shapes. However, you can do it as well with Ansys mesh software, and here is my recommendation:
1- I believe you need to remove all these edge sizing and enable adaptive sizing, approximate, and curvature features to reduce your skewness value.
2- inflation is not necessary you may use edge sizing instead.
3- Simplicity is king, I guess try to simplify your plan for meshing as I mentioned at #1 and use automatic constraint meshing. What I mean by that is that you need to specify the points of interest and let the computer does the rest.

Last year (August 2020) I uploaded the algebraic approach to the construction of a regular nonagon DOI 10.13140/RG.2.2.26286.95044/1 which in fact was the trisection of an angle of 60 degrees and so the tangent of the angle of 20 degrees was found to be 0.36387622008. Some years ago (2014) I published with IOSR Journal of Mathematics a paper for the trisection of every angle equal or less than 180 degrees the "Angle Trisection by Straighedge and Compass Only". A trisection, done by the intersection of two circumferences. Now, taking for trisection an angle of 60 degrees, for the intersection of the two circumferences we get the system of equations:
x^2 + (y + sqrt27)^2 = 36
(8 - x)^2 + y^2 =49
and the tangent of the angle of 20 degrees to be: y/(3-x) = 0.36345134567644, differing from the one calculated last year with the algebraic approach to the construction of the regular nonagon.
Where do you think that the difference of the two calculations of the same tangent is due?

Dear Global Research Community,
Have you ever worked with the concept of Decolonial Intersectionality (Salem, 2014; Kurtiş & Adams, 2016; Mollett, 2017)?

I have been pondering about the relationship between these two important topics of our data-driven world for a while. I have bits and pieces, but I have been looking forward to find a neat and systematic set of connections that would somehow (surprisingly) bind them and fill the empty spots I have drawn in my mind for the last few years.
In the past, while I was dealing with multi-class classification problem (not so long ago), I have come to realize that multiple binary classifications is a viable option to address this problem through using error correction output coding (ECOC) - a well known coding technique used in the literature whose construction requirements are a bit different than classical block or convolutional codes. I would like to remind you that grouping multiple classes in two superclasses (a.k.a. class binarization) can be addressed in various ways. You can group them totally randomly which does not dependent on the problem at hand or based on a set of problem-dependent constraints that can be derived from the training data. One way I like the most stays at the intersection point of information theory and machine learning. To be more precise, class groupings can be done based on the resultant mutual information to be able to maximise the class separation. In fact, the main objective with this method is to maximise class separation so that your binary classifiers expose less noisy data and hopefully result in better performance. On the other hand, ECOC framework calls for coding theory and efficient encoder/decoder architectures that can be used to efficiently handle the classification problem. The nature of the problem is not something we usually come across in communication theory and classical coding applications though. Binarization of classes implies different noise and defect structures to be inserted into the so called "channel model" which is not common in classical communication scenarios. In other words, the solution itself changes the nature of the problem at hand. Also the way we choose the classifiers (such as margin-based, etc) will affect the characterization of the noise that impacts the detection (classification) performance. I do not know if possible, but what is the capacity of such a channel? What is the best code structure that addresses these requirements? Even more interestingly, can the recurrent issues of classification (such as overfitting) be solved with coding? Maybe we can maintain a trade-off between training and generalization errors with an appropriate coding strategy?
Similar trends can be observed in the estimation theory realm. Parameter estimations or in the same way "regression" (including model fitting, linear programming, density estimation etc) can be thought as the problems of finding "best parameters" or "best fit", which are ultimate targets to be reached. The errors due to the methods used, collected data, etc. are problem specific and usually dependent. For instance, density estimation is a hard problem in itself and kernel density estimation is one of its kind to estimate probability density functions. Various kernels and data transformation techniques (such as Box-Cox) are used to normalize data and propose new estimation methods to meet today's performance requirements. To measure how well we do, or how different distributions are we again resort to information theory tools (such as Kullback–Leibler (KL) divergence and Jensen-Shannon function) and use the concepts/techniques (including entropy etc.) therein from a machine learning perspective. Such an observation separates the typical problems posed in the communication theory arena from the machine learning arena requiring a distinct and careful treatment.
Last but not the least, I think that there is deep rooted relationship between deep learning methods (and many machine learning methods per se) and basic core concepts of information and coding theory. Since the hype for deep learning has appeared, I have observed that many studies applying deep learning methods (autoencoders etc) for decoding specific codes (polar, turbo, LDPC, etc) claiming efficiency, robustness, etc thanks to parallel implementation and model deficit nature of neural networks. However, I am wondering the other way around. I wonder if, say, back-propagation can be replaced with more reasonable and efficient techniques very well known in information theory world to date.Perhaps, distortion theory has something to say about the optimal number of layers we ought to use in deep neural networks. Belief propagation, turbo equalization, list decoding, and many other known algorithms and models may have quite well applicability to known machine learning problems and will perhaps promise better and efficient results in some cases. I know few folks have already began searching for neural-network based encoder and decoder designs for feedback channels. There are many open problems in my oppinion about the explicit design of encoders and use of the network without the feedback. Few recent works have considered various areas of applications such as molecular communications and coded computations as means to which deep learning background can be applied and henceforth secure performances which otherwise cannot be achieved using classical methods.
In the end, I just wanted to toss few short notes here to instigate further discussions and thoughts. This interface will attract more attention as we see the connections clearly and bring out new applications down the road...

I've been having similar random thoughts over the two topics. As a matter of fact, I'd like to think about learning in the more genernal sense, not limited to machines. But when I put keywords like 'coding theory', 'learning' etc. in google, most results are just about applying some information theoretical techniques in machine learning, while I'm looking for a deeper connection help me understand learning better. And your post is seemingly the closest thing to what I want.
To briefly summarise my idea, I think we can treat learning as encoding, similar to the last point brought up in your post. I have to admit my ignorance but I haven't found any works studying learning using the framework of coding theory, rather than just borrowing some convenient tools. You may have dug into the literature more since your post, please direct me to the right works/authors if you have found relevant materials.
I don't have a background in information theory, but I guess I know some naive basics of it. Many artificial neural networks can perform a denoising or pattern completion task -- Isn't that impossible from a information theoretical point of view? Why an output can ever be the 'denoised' version of any noisier input? Of course this is a stupid question, but it led me to realise that learning/training is like encoding and testing/responding is like decoding. Then I had to accept that a learning system with all its training data forms this information pathway that has a long (even permanent) lifespan, which should be shorter than the changing rate of the regularities underlying the data. Specifically, learning is a process for the system to compress the aggregated noise in the training data (coding types other than compression would be more fun, but I'm not discussing it here), it considers this as information and incorporates it into its learnable parameters (these things live longer than individual datum), and as a successful outcome the system becomes capable of denoising a test sample, which is in some sense similar to decoding an encrypted message with the correct codebook. In other words, I can think of learning as a procedure of the system minimising its lifetime entropy by data fitting. This idea is evidently hinted by the common use of error minimisation in terms of mimising loglikelihoods in machine learning, but was clearly spelt out in Smolensky's Harmonium, which is slightly different from Hinton's restricted Boltzmann machine in the goal of optimisation (involving entropy). Unfortunately I'm not experienced enough to explain the technical details.
From my perspective, I consider this research direction extremely important and relevant when it comes to continual learning. In a more classical, static data fitting or machine learning scenario, in theory the learning system could be embracing all the training data at the same time. Minimising lifetime system entropy is equivalent to reduce system uncertainty with respect to the training data at the exact moment it encounters data. However, this is clearly a non-realistic assumption for humans and for many AI applications. A more realistic data stream is more dynamic, and at each moment the system could only observe partially the data. Evidently if an artificial neural network tries only to optimise itself with respect to this imperfect information, it suffers from catastrophic forgetting. So people start to tweak the learning rules or the regularisers, etc. in order to fix the problem. I do similar things, too, but I feel a lack of theoretical guidance, as I consider there should be some information theoretical quantification of the difficulty of continual learning tasks (there are some primary but arbitrary classification now), at least for artificial tasks.
In summary, I believe an updated version for coding theory is needed for studying continual learning, because in this scenario the channel capacity of a learning system has to be affected by more than its instantaneous parameter (including structure) configuration, but additionally an integral over time of these parameters.

This is a model of a stiffened plate girder. The APDL code is provided below for its geometry generation. It is not getting meshed after gluing all the volumes. If the volume is subdivided in the intersection locations of the different volumes, then it can be meshed I think after gluing. But dividing them into small volumes in the intersection locations is a tedious process. How to do this in a simplified way?

Hello everyone, I'm struggling with a problem related to reinforcement learning. This is the scenario:
There is a four-way intersection in which some vehicles enter the intersection, and we aim to coordinate these vehicles according to their decisions to turn left, right, etc. Therefore, when we finish coordinating these vehicles, after a while, these vehicles will have left the intersection. Not to mention that we are dealing with a dynamic scenario in which vehicles enter the intersection randomly and we have to decide for them as fast as possible(decide for their priorities, velocities, etc.).
In order to diminish the costs of handling the problem in a centralized way, we assume that the vehicles themselves solve their coordinating problem in a decentralized way by acquiring the locational data of other vehicles.
I want to handle this problem with deep reinforcement learning. Actually, in my opinion, that would be nice to consider a multi-agent reinforcement learning method in which the agents act in a decentralized way and are trained centrally (CTDE). My assumption is that the agents in this scenario are the vehicles that are entering the intersection. Well, this is straightforward in the first place, but the problem is that I do not know how to model the problem. Because the system is multi-agent, I think I have to consider a separate DQN (DNN) for each vehicle, but these vehicles exist in the system for a short period of time, and after that I schedule them, they are gone. This is to say that I train the respective DQN of the vehicle when it is present at the intersection, and then I delete the DQN of that vehicle when it leaves. This is perplexing!
What do you think I can do about this problem?

Answer
Yes, I'd like to have a decentralized system with centralized reward function for all of the existing vehicles.

However, after applying no-lane change near the traffic signal, I found the picture 2 for EB direction. Actually, those two vehicles from picture 2 would like to turn left, but they are in no turning section. Therefore, they are not moving.
How may I apply no-lane changing near an intersection?
Relevant answer
Answer
Hi,
You shall make the connector sufficienctly long (say 100ft as per your requirement), and enable the NoLnChRAllVehTypes and NoLnChLAllVehTypes parameters in the link properties for the connector. Also, to prevent vehicles from having to make last minute decisions on changing the lane to follow a desired route, introduce the vehicle route decision point well upstream of the connector.
Hope this helps.

Intelligent transportation systems provide many advantages as part of our daily lives. One of the most common applications of these current and increasingly widespread systems in our cities is intelligent junction control. The scope of the intelligent junction control concept which includes different approaches and algorithms, is quite wide. It is known that it needs realistic and objective technical knowledge to guide decision makers correctly. In this sense, what do you think the definition of intelligent intersection should include? Is a high-cost intersection control system with a lot of equipment always necessary? Or are the lower cost solutions that enable multi-plan control by only increasing the number of control programs? What should be the threshold or the transition point for the preference? Is it sufficient to make only cost-benefit analysis? To what extent should social benefits be taken into account for feasibility analysis? Sharing your views on this issue can be beneficial to many researchers and interested parties and can contribute to the spread of sustainable transportation (traffic management) systems.

I heard recently from an agency that they consider that signals operate effectively if they change light from green to yellow to red, in that consecutive order and without interruption. So, what exactly is a good control is like a "beauty in the eye of the beholder". So, an agency first needs to be comfortable with level of operations quality or misery that non-optimal control generates to participants in traffic stream. Then, an agency needs to define operational measures (or objective functions more formally) that they would like to improve. If there is more than one such measure then they should be able to judge how to weigh each criterion. At this point we probably already lost their interest and attention as this is usually an overwhelming task for them but if anyone survives this point then it makes sense to talk about level of ITS equipment, primarily for sensing purposes and then finally the quality of the control algorithm. So, what we in academia usually put at forefront of our research (control algorithms) folks in practice usually care less.

VennPainter uses set-theory to generate Venn diagrams. The intersection is defined as follow:
A \ B ¼ fx : x 2 A ^ x 2 Bg
and its complement:
B n A ¼ B \ A∁ ¼ fx : x 2 B ^ x 2= Ag
Technically, integer ax is assigned to label element x.
ax can represent the following: 8x 2 ax ¼ i¼ [n Xn Ai; 1 ≤ n ≤ 31 bi; 1 ≤ n ≤ 31 and bi ¼ i ¼ 1 i ( 2i—1; x 2 A 0; x 2= Ai
Thus, if ax1 = ax2, then x1 and x2 belong to the same intersection. VennPainter labels every intersection Um with an integer cUm in the Venn diagram (S1, S2 and S3 Figs). If ax ¼ cUm , then x 2 Um. The flowchart (Fig 3) shows how VennPainter works.

Next, x1 does not belongs to A2, and that is why we have b2 = 0;
Next, x1 belongs to A3, and that is why we have b3 = 2^2 = 4;
Next, x1 does not belongs to A4, and that is why we have b4 = 0;
Finally, x1 belongs to A5, and that is why we have b5 = 2^4 = 16.
By definition, we have ax1 = b1 + b2 + b3 + b4 + b5 = 21.

In an academic sense, social class is a reality directly linked to academic attainment, heritage, financial status and social positions. Hence an individual's knowledge of the literary and relevant theories and concepts naturally will be applied in making an analysis. However, these variables I mentioned, in many ways contribute to an individual's social construction of reality, inclination and attributions. Beyond and within academic stipulations of analysis of texts, individuals view texts based on the aforementioned persuasions and worldviews.

Hey !
I found this really interesting article ( ) that explains the utility of a expansion design following the nozzle to create a velocity gradient and forces the breakup of the inner flow to occur at the same point.
However, they added expansions of the continuous phase channels before the intersection, calling them "pressure reservoirs" and mentioned that it " stabilizes the water and oil phases" (see Fig 2 in the paper).
Is there a mechanic explanation for this stabilization, or a paper on this ? I couldn't find any other mentions of these pressure reservoirs in other papers, and I would like to have a more mechanistic explanation before adding them to my designs.
Does someone have an idea about the justification of these pressure reservoirs, or experience using them compared to more standard designs ?
Many thanks for your help,
Best wishes,
Romain
Relevant answer
Answer
Disclaimer: not my area of expertise.
The single phase, stationary CFD sims are woefully inadequate to explain what's going on.
Based on Fig 5, it looks like the primary water channel is pushing forward (thread growth) and creating back pressure on the oil stream. Oil flow at the water channel inlet would be slow, instead it's feeding directly at the orifice (only point of escape) and compressing the water at the nozzle. The time lag here creates a small thread of water that went past the nozzle as the oil compresses, and that is the droplet that pinches off. Unfortunately (I imagine), as it pinches, the oil compression force drops because there is more room for oil flow. This would destabilize the compression mechanism, and the string of water between the water inlet and the nozzle falls apart, giving those small satellite droplets. If I were designing this, I would want the pinching to occur as close to the water inlet as possible, so the back end of the water string stays coalesced with the inlet stream. I.e., I would guess that including this pressure reservoir is not a good idea.
Frankly, I'm not sure how the downstream geometry affects this at all. Did I miss a real world comparison to alternative geometries? If anything, I would be worried about flow recirculations at the outlet of the triangular geometry creating back pressure effects that vary with total flow rate. Not a big fan of unpredictable dynamics, dead volumes, and would use a continuous, smooth bubble geometry to guide the flow... If it's even necessary.
Hope that helped, Romain.

15 min time interval in VISSIM is it inserted in VISSIM as volume veh/15min or as flow rate veh/hr. in case veh/hr, does VISSIM clear the intersection after every 15min and enter new 15 min flow rate for the following 15 min ?
Relevant answer
Answer
The vehicle input is always vehicles per hours. You can see this, when you move with your mouse over the attribute name in a list - see screenshot (1).
When you have several time intervals of 15min, Vissim will change the vehicle input rate every 15min rate. The network will not be cleared after each interval.
By the way, please note that per default settings the vehicle input is stochastic. I.e. if you enter 1000 veh/hr for a 15min-interval, the number of vehicles in your simulation will be around 250 veh/15min, but not exactly. That is a nature of a stochastic simulation, however, you can change this by setting the attribut VolType to "Exact" - see screenshot (2).

That is due to the degradation of the electrodes you are using, for example if your battery configuration is LiFePO4/Li, the changes in profiles depends on degradation of the cathode, Li-anode and/or degradation of the electrolyte you are using.

How to estimate the vehicular emissions at traffic intersections using emission factors and traffic volume count ? What should be the zone of influence in terms of distance in this case ?
Relevant answer
Answer
I have not worked in this area for a while but are asking something that is extremely difficult as there are many variables.
You also have to think 3D as know one traffic survey equipment manufacturer that put CO sensors in equipment and were horrified that at an intersection the pollution level at an adult height was 1/10th of that at the height of a baby in a pram (and at that age taking into account physiology and brain development could be catastrophic). It was logical when think about it as that is where the exhaust pipes are!
Free flowing traffic will also tend to drag the pollution and created a turbulent flow to help disperse which is what the early study by the equipment manufacturer I mentioned found.
Near the exits of tunnels you can get a massive increase in pollution but depends upon the surrounding buildings and wind tunnelling effects that may contain or disperse the pollution. The same would apply in a city and you would be aware of temperature inversions that help to contain pollution.
Good luck.

The deviation rate of the second law of thermodynamics is 14.6%. See the following figure (or annex). It's not a case.
* * * * * * * *
A: Figure 1 is from the authoritative book "Handbook for Estimating Gas-liquid Physical Properties", which calculates enthalpy change H1 by equation of state. From Fig. 1A, the accuracy of the equation of state is very high, but the enthalpy deviation rate derived is very large. The theoretical basis of the derivation is the thermal 2 differential equation.
B. Drawing with the deviation rate of state equation (< 1%) and enthalpy variation deviation rate (Fig. 2), without considering two abnormal points, the deviation rate is regularly arranged. The deviation rate of fitting line and Y axis intersection point C (0,0.146) and thermal 2 differential equation is 14.6%.

Sorry, but Fig. 1 is nonsense. One cannot predict the 2nd virial coefficient from the 2nd Law. It is necessary to have some experimental data or a pair potential.
P(V, T, E) is not a meaningful expression for a pure fluid. There can only be two independent arguments.

Consider the following cases, where i have put my understanding
Notation - 0+ = tending to zero
{b} = singleton set
  1. lim (n-->infinity) (1/n) = 0+
  2. lim (n-->infinity) (n/n) = lim (n-->infinity) (1) = 1
  3. Step 2 can also be looked as lim (n-->infinity) ((1/n)/(1/n)) = 0+/0+= 1 (Here both 0+ are same and they are not exact 0)
  4. lim (n-->infinity) (n2/n) = infinity
  5. step 4 can also be viewed as lim (n-->infinity) ((1/n)/(1/n2)) = 0+/0+= infinity (here both 0+ are not same and one 0+ is like infinite times the other. Which is again a conclusion that 1/n or 1/n2 with limit n goes to infinity is exact zero)
Now the real question is this from probability theory or set theory.
I found this description of singleton as
{b} = infinite intersection over 'n' of (b-1/n , b+1/n]
but according to my understanding(as above), it still should represent a range of real number and not single point. For that intersection to result in a point, 1/n should be exact zero.
These two descriptions, one from probability theory and other from calculus doesn't seem to agree to each other according to my understanding.
Can you please tell where i am doing wrong ?
I might have used some terminologies carelessly, but i hope you got the point what i am trying to ask.
Thanks
